Thank you KOPRI for inviting me to the 29th International Symposium on Polar Science and the LIONESS workshop this week in Incheon Seoul, SK! It's great to be part of an exciting project on sea ice in the Amundsen Sea by Thwaites Glacier.

Last week’s ‘unlocking the past’ exhibition at the @royalsociety showcasing the potential of ice cores with the @BAS_News to better understand our past and present climate and how it may change with climate change.

🚨📰Excellent work led by Ashleigh Womack @MARIS_UCT on how storms affect differently Antarctic marginal ice zone drift during #winter sea ice growth and #spring sea ice retreat 📰🚨

Glad to have been part @SCALExperiment ⛴️🇦🇶🌬️🌊🧊

Really happy that this paper is finally out and that I got to be a part of it! Congratulations and thank you @riesna19 ❄️🌊

Audh et al., present biogeochemical data for young and growing sea ice in the Antarctic marginal ice zone and challenge the assumption that winter sea ice is biologically inactive ❄️❄️❄️ #AGUPubs

We are still celebrating ✨International #WomeninEngineering Day✨. We showcase how #earlycareer women link #polarscience to their respective engineering disciplines. @siobhanajohnson researches the #physical and #chemical properties of sea ice at the @BAS_News @Cambridge_Uni

Finishing up a good week at #egu2023 with my poster session in the @EGU_TC division on fatty acids in sea ice around Antarctica.

This work is done with @GiorioGroup and @BAS_News with my supervisors @chiara_giorio and Liz Thomas.

[Dr. Robert Rohde @RARohde]

This is getting ridiculous.

OISST provides a real-time daily index of ocean surface temperature (60 S - 60 N). For the last month it has been continuously reading higher than in any previous year and still shows no sign of settling.

[Siobhán Johnson @siobhanajohnson]

It's finally out! Go check it out 🇦🇶
Thank you to all my co-authors for your tireless help to finish this 💙

New JOG paper! "Physical and morphological properties of first-year Antarctic sea ice in the spring marginal ice zone of the Atlantic-Indian sector” by S Johnson, R Audh, W de Jager, B Matlakala, M Vichi, A Womack, T Rampai -> https://t.co/ysLKLaN7p0 @UCT_Research @MARIS_UCT

[Siobhán Johnson @siobhanajohnson]

It's finally out, after almost three years of working on it! A new review paper about laboratory-grown sea ice for sea ice research:

I'm very excited to share with you my last paper on improving the definition of the #Antarctic marginal ice zone. Thanks to all my colleagues in @CRiceS_H2020 @ClimateWhales and the scientists of the @SCALExperiment and @MARIS_UCT

Thank you everyone who attended the @SCAR_Tweets @AntClimNow workshop at @BAS_News this week. The three days went so quickly, with stimulating presentations and discussions.

[Siobhán Johnson @siobhanajohnson]

Delighted to announce that I am officially starting my PhD at the University of Cambridge in October with the @BAS_News. Excited to continue to delve into the interdisciplinary science of the polar regions and learn about the role of sea ice in climate past reconstructions.
